[Ultrasonic dopplerography and photoplethysmography in the diagnosis of Raynaud's syndrome].

Data on the studies of the blood flow in finger vessels in 45 patients with Raynaud's disease by means of ultrasonic dopplerography and photoplethysmography are given. The control group consisted of 30 persons. The use of a cryotest showed significant differences in arterial segmental blood flow of the hand fingers in patients with Raynaud's disease and in those of the control group. The mentioned methods are noninvasive, give sufficiently informative results providing an objective assessment of the nature of vascular disorders in Raynaud's phenomenon of different genesis.
